Sex hormones are present in 70-year-old women, but the values are significantly lower than in premenopausal women. Sex hormones are physiological hormones secreted by the gonads of mammals, as well as the placenta and the adrenal cortex, etc. In women, estrogen and progesterone are mainly secreted by the ovaries, while in men, androgens are mainly secreted by the testes. In older women, after menopause, ovarian function declines and the gonads atrophy, so the level of sex hormones will drop significantly. In general, 70-year-olds may have some level of sex hormones, just in very low amounts, because the adrenal glands of the body also produce small amounts of sex hormones. The physiological role of hormones is complex, with functions such as regulating the body’s metabolism, influencing the development and activity of nerve centers, and affecting the ability to learn and remember. Elderly women can suffer from calcium loss due to the decline in estrogen levels, resulting in osteoporosis, etc. Such people can be treated with hormone supplements under the guidance of a doctor.
